LOOM.

SPECIFICATION forming part f Letters Patent No. 678,27 9, dated July 9, 1901.

Application led November 13,1900. Serial No. 86,326. (No model.)

T0 ctZZ whom, it may concern:

Be it known that I, GEORGE R. RAGE, a citizen of the United States, residing in the city and county of Philadelphia, State of Penn;

Sylvania, have invented a new and useful Improvement in Looms, of which the following is a specification.

My invention consists of an improvement in a loom wherein I provide means for sup-Vv xo porting a warp-beam above the frame of the same, whereby the speed of the warp-beams may be varied without aecting'each other and the size of the warp-beam can be very greatly increased. I5 It further consists of an improvement in tension devices therefor. l

It further consists ot noveldetails of construction, all as will be hereinafter set forth. Figure l represents an end elevation of a 2o portion of a loom embodying Vmy invention. Fig. 2 represents a side elevation thereof.

v Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a loom which, excepting the features of my invention applied thereto, is a well-known construction.

C designates brackets, which, attached to the frame B of the loom, form the bearings 3o for the journals D and E of the rollers F and Q, said brackets being also adapted to sup,

port a Warp-beam G, which is provided with pulleys II, around which passes a rope or cord J, one end of which is secured to a pin K in 3 5 the frame B of the machineand the opposite end being secured to a rod or lever L, which is provided with a weight M, which is adjustable thereon, said rod or lever L having one end engaging the tongue N and constituting 4o the fulcrum thereof. The usual construction of Warp-beam P is employed, as heretofore, with the usual tension device, the yarn or thread from the warp-beam G being adapted to pass down underthe roller. Q, while the yarn or thread from the warp-beam P passes over the roller F and beneath the roller Q.

It will be seen that by employing this bracket the substitution of warp-beams can be quickly and expeditiously made and that the speed of 5o the warp-beams can be varied as may be found c necessary in the operation, while the larger warp-beam may be used, thus obviating the necessity of numerous changes which now arise.

It'will be further noted that the economy 55 of space Will be obtained by placing said warp-l beam above the frame of the loom and substantially vertically above the lower warpbeam.` y

It will be apparent that slight changes may 6o be made by those skilled in the art which will come within the scope of my invention, and I do not therefore desire to limit'myself to eX# act construction herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In .a loom, a warp-beam, a bracket' se# cured to the frame of said loom, a warp-beam carried thereby, journals on said bracket,- 7o

and rollers carried in said journals whereby the said bracket, rollers and warp-beam, can

be removed from said loom,- said rollers being adapted to receive the yarn or thread, one from one beam and the other from the other warp-beam.

2. In a loom, a warp-beam, a tension-bar,

a strap suitably connected therewith and with said beam, a second warp-beam, a suitable lever connected with said tension-bar, and a So strap suitably connected with said lever and with said second warp-beam.

3. In a loom, a warp-beam, a tension-bar,

a friction-band connected therewith and serving to govern the tension of said warp-beam, a second warp-beam, a weighted lever connected with said tension-bar, and a frictionband attached to said lever and serving to govern the tension of the second warp-beam.

4. In a loom, a lower warp-beam, a tension- 9o bar suitably connected with said lower warpbeam to control the tension thereof, a bracket secured to the frame of said loom, an upper warp-beam carried thereby, a weighted lev'er connected with said tension-bar and with said upper warp-beam to control the tension thereof and rollers carried by said bracket which are adapted to receive the yarn Vor thread, one from the lower warp-beam and the other from the upper warp-beam.

GEORGE R. RACE.
